Application ld August 30, 1930! Serial No. 478,887.

This invention pertains to improvements in that type of screens shown in my Patent No. 1,715,024, issued May 28, 1929. The purpose of the present invention is to so construct a `5 screen of the character shown in this patent that insects will not be able to see rays of light transmitted directly through the vents through which such insects are expected to pass when leaving a room and going to the L i0 outdoors; to so construct a screen of the char acter indicated that insects on the inside of the screen will be able to see reflected light passing from the outside through the vents inwardly and downwardly, but those outside and such further objects, advantages and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combina- 210 tion, construction and arrangement of parts illustrated in the accompanying drawings and, while I have shown therein what is now considered the preferred embodiment of my invention, I desire the same to be understood 25 as illustrative only and not to be interpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof, Fig. 1 is an illustration in elevation of a window frame having a screen 30 constructed in accordance with my invention mounted therein; Fig. 2 is a vertical section through the construction shown in Fig. 1; Fig. 2A is a vertical section of a screen having my invention applied to the upper cross bar only; Fig. 3 is an enlarged section through a rail of the screen to illustrate more clearly the construction of my present invention; Fig. 4 is a view similar to Fig. 3 of a modified form of this construction.

Referring more in detail in the annexed drawings, the window casing is denoted by the numeral 1, while the numeral 2 denotes broadly the screen mounted in the casing. This screen is shown as having a bottom f5 cross rail 3, a middle rail 4, and a top rail ,5.

InFigs. 1 land 2 I have shown the middle rail as provided with vents'to permit the escape of insects, but I prefer to have these only in the top rail 5 as shown at the top of these W two figures. This permits the screening ma- '35'0 terial 6 to be stretched from end to end of the screen instead of being cut oi as illustrated in Figs. 1 and 2. It is obvious that the screens may be constructed in either way, l as maybe desired by the manufacturer. 5:5

As illustrated most clearly in Fig 1, a series of supports 7 are formed along or secured to the outward face ofthe frame member 5 p f to serve as supports for the screen material 6, v I5 Will not be able to see light from the inside;

keeping the same spaced away from the face 8'of the bar. Preferably a channel 9 is formed in one face of the bar, said channel having an inner portion or bottom which Vis parallel with the inner and outer faces of f the rail. Connecting this face with the outer `face is' an inclined face 10 or 10a. the latter 10. The rib A12 extends'in far enough so that no direct rays of lightcan pass from the outside inwardly and downwardly through' theV channel 9 and strike upon the face8." All i5 `raysof light entering this channelfrom the 1 outside must either strike the face. 10 or-the bottom face of the channel 9, while rays from inside the room will be shut out by the lower l partV of theA rail 5, even though `shining upwardly fromdirectly below, or else, thefew which pass this point are stopped bythe ridge 12. The surface 13a of the molding =11a isv curved slightly to correspond with the curvature of the surface 10a, but it will be '85 recognized that the two structures shown in :these twofigures are clearly equivalents.

It is apparent that a channel 9 is formed by cutting a groove along one face ofl a bar .5 andthen cutting notches inthe rib left90 trated in Figs. l and 2, wherein a vent is formed in the middle bar 4, as well as the upper bar 5, the screen may have perforations formed therein to register with the channel 9, thus permitting the insects to escape through the screen. While this.

would obviate-the inconvenience and expense of cutting the screen into short `lengths and applying the same, it would on the other hand make additional expense in forming the perforations through the screen. the whole, it is believed preferable to vmake the screens with the outlets at" the upper end only, as shown in Fig. 2A, omitting the outlet at the middle cross bar.

Having now described my invention, I claim: l i

l. In a screen of the character described, a

outwardly to support the netting away from the body of the cross member, and a screen holding bar secured against the netting and projections and having on its inner face a projection extending into the groove in the cross bar so as to prevent rays of light shining directly through the groove in the cross bar, between the latter and the holding bar.

In witness whereof, I hereunto subscribe my name to this specification.

RANDOLPH ARBUCKLE.

cross bar having a channel in the outer face thereof, supporting elements along said face and between the channel and the lower edge of the bar, a molding secured against the supporting elements and having on its inner face a rib extending into the channel to form an obstruction for rays of light between the lower edge of the bar and the upperA edge of the channel.

2. In a screen of the character indicated, having a cross bar provided on its outer face vwith a channel, said channel having its upper face inclined, said bar having a rib between said channel and the inner edge thereof, said rib being formed with vent openings for'the escape of insects from inside the screen, a molding secured to the outer face of the bar and having a portion overlying theV vent openings and another portion overlying the channel, the portion overlying the channel having a rib formed upon its'inner face to project into the channel and having its upper face inclined so that it will be substantially parallel with the inclined face of the channel. 1

3: A structure as defined in claiml 2 in which the upper face of the molding is flat. 4. A structure as defined in claim 2 in which the upper face of the molding is curved.

5.A screen comprising a frame having side members and transverse members to support the screen netting, netting mounted on and secured to said frame, a cross member ofA the frame having a groove on the outer face thereof, vthe inner edge of the groove cross member having projections extending
